I’ve recently read articles on this subject claiming a high depletion of minerals in current topsoil nationwide. Came across this they use it in a mineral supplement, I’m taking that and something is working . Anyway, not hawking anything but they also sell a powerdered form just the minerals for agriculture. Somewhere on that site is some info regarding the results. Info is down the page a little.
Just found it interesting,
